Porsche unveils latest generation 911 GT3 car
Debut for the newest generation of the Porsche 911 GT3 R.
The new Porsche 911 GT3 R will be unveiled to the public at this year’s 24 Hours of Spa-Francorchamps. From the 2023 season, Porsche customer teams can campaign the new racing vehicle in worldwide motorsport events that adhere to the GT3 regulations. The vehicle is based on the latest 992-generation 911.
With the latest generation of the 911 GT3 R, Porsche unveils a new customer racing car. The new challenger for GT3 series around the world is based on the current 992 generation and will be ready to race at the beginning of the 2023 season. Development began in 2019. Priority was given to further improving the driveability for professionals and so-called gentleman drivers, as well as tapping larger performance reserves for different Balance of Performance (BoP) classifications. Another focus was on streamlining the handling of the race car for the teams and reducing the running costs.
“The new 911 GT3 R has big shoes to fill,” says Michael Dreiser, Sales Director at Porsche Motorsport. “Its forerunner has won almost everything there is to win in the GT3 scene in four seasons since 2019.
Its stand-out successes include overall victories at the 24-hour races at the Nürburgring and also here at Spa-Francorchamps. Raced by our customers, the predecessor scored class victories at the 24 Hours of Daytona and the 12 Hours of Sebring.
The new model faces a massive workload in the hands of the Porsche customer racing teams.” After the GT3 class was announced as a professional category in the North American IMSA series, the FIA WEC World Endurance Championship follows suit: From 2024, GT3 racing cars such as the new 911 GT3 R will be eligible to take part in the 24 Hours of Le Mans for the first time.
At the core of the new racing car is the near-standard engine based on the 992-generation 911 power plant. Like in the previous model, it is a water-cooled flat-six engine with four-valve technology and direct fuel injection. The main new development is the displacement: like the 911 RSR, the capacity of the new 911 GT3 R has increased by a good five per cent from 3,997 to 4,194 cc.
This has boosted the engine’s peak output to around 416 kW (565 PS). First and foremost, however, Porsche has optimised the torque and power curve across the entire rev range. Consequently, the new 4.2-litre six-cylinder is better suited to gentleman drivers.
The high-revving six-cylinder manages without turbocharging and sits in the classic rear position, thus enhancing traction and braking.
The optimised positioning of the central pivot points at the front axle frees up space for the aerodynamic “race underfloor” concept. Like in the 911 RSR, this elevated underbody allows for a clean flow of air to the rear diffuser and reduces the pitch sensitivity of the racing car – i.e. a high rake under braking.
The rear wheels have moved a little further back, which extends the wheelbase from 2,459 to 2,507 millimetres. This also reduces the load on the rear tyres and improves the consistency of the tyres’ performance over longer stints.
The new 911 GT3 R is just the second racing car from Porsche Motorsport to be based on the current 992-generation 911 after the 911 GT3 Cup. Its lightweight body with an intelligent aluminium-steel composite design draws on the production model, albeit with major modifications for use in the 911 GT3 R. Almost all body components are made of lightweight carbon, including the front and rear lids, doors, side panels, rear wing and roof. The wheel arches are made of aramid fibres.
In terms of safety, the new 911 GT3 R follows an uncompromising approach. The seat has moved closer to the centre of the car. This enabled Porsche to optimally adapt the more ergonomic seat position to the improved roll cage and the newly developed FIA side impact protection. Like in the forerunner, the steering wheel and pedals can be adjusted longitudinally to suit the driver. Porsche specialists took another close look at the six-point safety harness: the tongues now slide even faster into the clasp via special ramps – saving about a second during pit stops for driver changes.
The steering wheel design also received further upgrades on the previous model. It incorporates elements that have proven themselves in the latest generation 911 GT3 Cup and 911 RSR race cars. The 10.3-inch display, for example, comes from the successful one-make cup racer, with the multi-switch concept adopted from the Le Mans class winner.
